ENERGY OF TIDAL POWER
The Bay of Fundy, (40‘ high), which is the site of the highest tide in the world, is shaped like a horn, which was developed by helical waves over millions of years. It is the same shape found at Anchorage, Alaska (27′ high), because they were created by the same energy of helical waves. The wave of this system causes the water to increase its speed as it is deflected at each turn. The narrowest point of the Inlet at Anchorage, Alaska has mid-channel speeds up to six knots with an average of 3.8 knots that produce amazing tidal power.
Eight potential project sites were identified in Nova Scotia that have both flood and ebb peak tidal current surface velocities averaging at least 1.5 m/sec (3 knots). The mean extractable power (15% of the mean total depth-averaged power) at each of these sites is indicated below:
(1) Cumberland Basin – 6.5 MW
(2) Minas Channel – 131 MW
(3) Minas Passage – 166 MW
(4) Cobequid Bay – 6.3 MW
(5) Digby Gut – 4.9 MW Could be set up as an ebb tide system…
(6) Petit Passage – 9.2 MW
(7) Grand Passage – 6.6 MW
(8) Great Bras d’Or Channel – 1.4 MW Could be set up as an ebb tide system…
The very efficient, mostly propeller type hydraulic turbines developed for high river dams are inefficient, complicated and very expensive for low-head tidal power application.
REMEMBER: The threshold for economic viability is possible in tidal currents with velocities over 3.1 m/s (6 knots). Most of the ocean currents have a velocity of 1.5 to 2.5 m/s (the California Current is under 0.5 m/s): that is why there has never been a successful commercial ocean current power system.
Extracting Tidal Energy
Kinetic Energy (KE)= ½ × A × V ³ x efficiency (A = area swept; Velocity)
Competition KE= .5 x 3.0 m² x (2.5 m/s) ³ x .20 = 5 kW/turbine (Propeller turbines are less efficient than helical turbines.)
- The most critical factor is the Velocity of the flow.
- A tripling of the Velocity from 2.5 m/s multiplies the Kinetic Energy (KE), by the formula:
HUG KE = .5 x 3.0 m² x (7.2 m/s) ³ x .30 = 180 kW/turbine: 36 x more efficient (The lowest velocity in the Midas Passage is 4 m/s)
Small changes in velocity can greatly alter Power Density.

OUR NORTHYDRO STRATEGY
- Stage 1 To capture energy from Run-of-River, Rapids and Waterfalls with the HUG
- Stage 2 To introduce a smaller version of the HUG: for Fish and Hunting Camps
- Stage 3 HUG Hydro electricity and irrigation in remote areas: to support work in Africa.
- Stage 4 To Introduce the HUG Water Transfer System to crisis area
- Stage 5 To introduce commercially viable HUG Tidal Energy
GREEN HYDRO POWER STATIONS The installation of most of very low head sites is technically feasible, but civil works give rise to high costs, resulting to economically enviable projects. To solve this problem, one must design a new machine using a completely different philosophy to equip such sites. The study of current turbines reveals that they were all invented on the basis of a poor understanding of hydrodynamics, and a consequent false premise.
MOBILE HUG: The HUG development is an exciting breakthrough in green energy. Small batches of HUG turbines can be installed with only a short period of 12 to 18 months between investment in the technology and the time when revenue starts to flow: it is modular, relatively easy to install and highly scalable.
PRE-FABRICATED HUG Standardized pre-fabricated modules should make it possible to order this new product as a “power plant kit” just like ordering from a catalog. The HUG power plant uses standardized parts, so no custom engineering is necessary. A one-size-fits-all pathway could be ordered.
Why is the HUG Frictionless? When we direct the water to flow at its natural mode, it hugs the inner wall. This kind of vortex motion tends to accelerate and contract the stream of water. The less collisions improves the flow, i.e. the better ordered and more dense the flow will be. The net result is that the velocity of the flow in the HUG is four to five times faster than the river velocity.
RING of FIRE The Ring of Fire Potential will come down to one factor, which will make or break any prospects: Hydro Electricity. Enter the HUG!
LABRADOR ENERGY POTENTIAL Any new technology leads to new growth opportunities: HUG is a Patented Energy System that will literally change the face of our world as we know it.
